skin pigmentation

The image titled "Skin Pigmentation Diagram" illustrates the role of melanin in determining skin color, comparing the cellular structure of dark and light skin. Located in the epidermis, melanocytes produce melanin, which is then taken up by keratinocytes, influencing the skin’s pigmentation. This diagram highlights the distribution and density of melanin across different skin tones, offering insight into the biological basis of skin color variation. This article explores the mechanisms of skin pigmentation, the anatomical role of the epidermis, and the physiological processes that regulate melanin production.
